如何绕过将数据模型传递给 arguments 以避免事务太大异常？

Question

I'm trying to fix TransactionTooLarge exceptions. I can't find any main culprits in onSaveInstanceState .

However, when it comes to passing things to intents and bundles, I am seeing a lot of the follow type of code on a fragment.

companion object {

    fun newInstance(item1: Item1, item2: Item2): MyFragment {
        val fragment = MyFragment()
        val args = Bundle()
        args.putParcelableArrayList(ITEM_1_KEY, item1)
        args.putInt(ITEM_2_KEY, item2)
        fragment.arguments = args
        return fragment
    }
}

Essentially there's a bunch of code passing data models everywhere.

How do you get around trying to pass smaller objects in bundles to fragments?

These fragments basically just pick these up and use them. It feels difficult to avoid passing these through.

Answer 1

Convert Data Models to JSON and pass it or store it as String. I had faced a similar kind of issue, I had implemented the same way

Answer 2

Try to use middle man as ViewModel by viewModel you can attach same source of data between fragment and activity with the ability to update the data smoothly
